Arrangement for connecting the block units made up of several blocks of assembled control units for hydraulic systems

The invention relates to an arrangement for connecting the block units composed of several block units Control devices for hydraulic systems, in which the individual block units on mating surfaces un indirectly bear against each other and are held together by connecting means.

The main advantage of the so-called block design lies in the saving of connecting lines between the individual units, the associated small footprint and the closer amalgamation of the operating means.

It is known that the block control devices by means of several continuous and over the entire block

summarize length extending lag screws. The tensioning forces of these lag screws can be applied to the individual block units to the effect that the holes in which the control piston with are arranged displaceably with very little play, so deformed that the function or control piston is hindered. In addition, it is necessary for each block length to pull the appropriate screws Keep length in stock.

The aim of the invention is to create a mess to connect of the individual block units that have no effect on the piston bores. In addition, the Connection means, if possible, each be part of a block unit, so that the connection of a Block unit can be easily done with another. . ". ■" "

This object is achieved according to the invention by that separate connecting means are provided for connecting adjacent block units, which attack in the immediate vicinity of the adjacent mating surfaces.

In a preferred embodiment of the invention, screws are provided as connecting means, which support themselves with their head against an abutment within one block unit and with their threaded shaft in threaded bores in the adjacent one Block unit can be screwed in. The block units carrying the abutments are preferably included provided with a through hole through which a screwdriver or wrench can be used the screws passed through it. at the block units lying between the end units the thread is preferably cut in the through hole.

Especially in the case of block bodies made of light metal the abutment is expediently formed by sockets which are preferably screwed into the housing. The abutments can be arranged in a countersink in the socket, the diameter of which is larger than the diameter of the screw head.

About the screws during storage and transport To be able to accommodate within the block unit itself is preferably a hole behind the abutment provided, the diameter of which is greater than the diameter of the screw head and its length

is dimensioned so that the screw can be turned back so far that its shaft end with the mating surface of the block unit is substantially flush or even slightly receding behind it.

In the thread side of the block units can known threaded bushings are used.

Particularly in the case of block control devices that consist of a large number of block units, individual The housing can of the block units between the abutment and the thread are provided with lateral cutouts through which the screws are accessible from the outside.

Another embodiment of the arrangement according to the invention is characterized in that parallel to the mating surfaces in two opposite Sidewalls of the block units hats are provided, which are located on their to the mating surface ! Flank wedge-shaped to the outside, and that U-shaped strips are provided as connecting elements, the inner sides of the legs correspondingly are wedge-shaped and which are fastened by screws: in
